Heat Pipe-Based DEMO Divertor Target Concept: High Heat Flux Performance Evaluation

Round 1

Reviewer 1 Report

The author have taken a series of experiments to study the heat pipe evaporator operating limits with liquid inventory 1.5ml for heat flux until 1MW/m2 with two different type heat source. 

A few minor problems: 1. Some reference source not found, such as line 268, 290, 467. 2. Fig.12 and Fig.17 should be improved. The unit of horizontal axis suggested to use minute.

Reviewer 3 Report

The conducted experiments are clearly described in the paper. Some corrections are suggested:

1) English changes are required (here are reported some examples but still other are to be checked)

line 10 are considered to be

line 14 framwork

line 36 for the sintered structure, 

line 195 Taking into account

2) correction of the format style are required in 2.5 e.g. blank line from 219 to 223 

3) some of the reference link shower error (e.g. line 68 and other)
